H3C 6805 Switch IRF Config Example

H3C 6805 Switch IRF Config Example

1 背景

分布式存储业务上架2台H3C 6805交换机

2台6805 switch need to config IRF

Model : S6805-54HF

2 IRF config

配置步骤如下

• 第1台指定优先级，范围1-32，越大越优，本次我们配置为10
  • 将IRF port的2个物理接口shutdown，不然不让加入irf-port
  • 创建irf port，将2个物理口加入
  • 2个物理口打开
  • 激活IRF配置，并保存配置
• 第2台修改编号，默认为1，需要重启交换机
  • 第2台指定优先级，本次我们配置为1
  • 将IRF port的物理接口shutdown，不然不让加入irf-port
  • 创建irf port，将物理口加入 激活IRF配置，并保存配置
  • 2个物理口打开 这时交换机会检测到对端，第2台（优先级低的）会自动重启
  • 重启完成后，IRF完成
• 配置mad双主检测

2 以下为具体配置步骤及命令

2.1 第1台6805

2.1.1 指定优先级

irf member 1 priority 10

2.1.2 将需要加入irf-port的端口关闭

Interface range Hundred 1/0/27 to hundred 1/0/28
Shutdown

2.1.3 创建1个irf虚拟接口

irf-port 1/1 
Port group interface hundred 1/0/27
Port group interface hundred 1/0/28
Quit

2.1.4 激活irf配置，并保存

irf-port-configuration active
save force

2.1.5 打开物理接口

Interface range Hundred 1/0/27 to hundred 1/0/28
undo shutdown

把irf port的物理连线接好

2.2 第2台6805

2.2.1 修改设备编号

默认为1，修改为2, 修改后需要重启交换机生效

<H3C-2> system-view
[H3C-2] irf member 1 renumber 2
Warning: Renumbering the member ID may result in configuration change or loss. Continue? [Y/N]:y
[H3C-2] quit
<H3C-2> reboot

2.2.2 重启完成后指定优先级

irf member 2 priority 1

2.2.3 将需要加入irf-port的端口关闭

Interface range Hundred 2/0/27 to hundred 2/0/28
Shutdown

2.2.4 创建1个irf虚拟接口

第2台不能使用1/1, 要使用2/2

Irf-port 2/2
Port group interface hundred 2/0/27
Port group interface hundred 2/0/28
Quit

2.2.5 激活irf配置，并保存

irf-port-configuration active
save force

2.2.6 打开物理接口

Interface range Hundred 2/0/27 to hundred 2/0/28
undo shutdown

这时第2台会检测到第1台设备，因为第2台的priority低，所以会重启。

3 重启后确认IRF状态

4 配置mad双主检测

创建3层聚合接口，开启bfd，配置2个Ip地址

将2个物理接口加入聚合接口

interface Route-Aggregation99
 mad bfd enable
 mad ip address 169.254.1.1 255.255.255.0 member 1
 mad ip address 169.254.1.2 255.255.255.0 member 2

interface Ten-GigabitEthernet1/0/54
 port link-mode route
 port link-aggregation group 99

interface Ten-GigabitEthernet2/0/54
 port link-mode route
 port link-aggregation group 99

确认mad状态

<H3C-6805-IRF>  display bfd session
